Wood fiber reinforced polyvinyl chloride imitation solid-wood cabinet door panel and manufacturing method thereof

Abstract

The invention provides a wood fiber reinforced polyvinyl chloride imitation solid-wood cabinet door panel and a manufacturing method thereof. The method comprises the following steps: spraying atomized phosphoric acid to wood fibers while stirring to obtain phosphorylated wood fibers; in sequence spraying a silane coupling agent and melamine resin to the phosphorylated wood fibers and light calcium carbonate respectively while stirring, and drying to obtain the wood fibers and the light calcium carbonate which are both coated by melamine resin; mixing wood fibers coated by PVC resin, foaming agents, calcium-zinc stabilizers, chlorinated paraffin, dioctyl phthalate, stearic acid, and the melamine resin and the melamine resin coated light calcium carbonate to obtain a mixture; (5) successively carrying out kneading and extrusion, open-milling tabletting, film lamination on the upper side and lower side, mould pressing of embossed patterns, cooling shaping, cutting and trimming and periphery closing on the mixture. The cabinet door panel manufactured by the method is good in flame retardance and fire proofing, and high in content of the wood fibers and mechanical strength.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite materials and furniture decoration materials, and in particular relates to a polyvinyl chloride micro-foamed imitation solid wood cabinet door panel reinforced by flame-retardant wood fibers and a manufacturing method thereof. Background technique [0002] The cabinet refers to the platform for storing kitchen utensils and cooking operations in the kitchen. Cabinet and door panels are mainly made of solid wood, MDF, blockboard, tempered glass, aluminum alloy, etc. The kitchen is a place where food is cooked and water and fire are concentrated. Therefore, not afraid of water and fire invasion is the primary consideration for cabinet material selection and design. [0003] PVC resin is a kind of polar non-crystalline high polymer, there is a strong force between molecules, it is a hard and brittle material; the impact strength is low, it needs to be modified for impact resistance, an...

AI Technical Summary

Problems solved by technology

[0011] Although the above research work has achieved some beneficial results, it still fails to solve the problems of poor flame retardancy and interface compatibility of wood-plastic composite panels, and its flame retardancy and mechanical strength still need to be further improved.
